HELP SECTION
GREYS
Type: Task
Use: GREYS will write commands to a plot file for the execution of a
grey-scale plot for an image. Optionally a second image can be
represented as contours superimposed on the grey scale. The
images are assumed to be of type MA. Optionally, the locations
of slices (taken from SLICE files) and windows (given by
CLBOXes) may be overlaid.
Adverbs:
DOCONT......IF > 0 requests that contour overlays be done. At least
one of IN2NAME, IN2CLASS, IN2SEQ, and IN2DISK must also
be specified.
DOCOLOR.....If > 0, do a true-color picture using INNAME if it is an
RGB cube to give all three colors or using INNAME,
IN3NAME, and IN4NAME as the red, green, and blue images
respectively. RGB cubes are made by RGBMP, TVHUI, MCUBE
(with PUTHEAD), and LAYER. If <= 0, take one plane of
INNAME as a grey-scale image.
INNAME......Image name for grey scale. Standard defaults.
INCLASS.....Image class for grey scale. Standard defaults.
INSEQ.......Image seq. # for grey scale. 0 => highest.
INDISK......Disk unit # for grey scale. 0 => any.
Optional contour image: may be same image as grey scale
All blank or DOCONT <= 0. -> no contours
IN2NAME.....Image name for contours. Standard defaults.
IN2CLASS....Image class for contours. Standard defaults.
IN2SEQ......Image seq. # for contours. 0 => highest.
IN2DISK.....Disk unit # for contours. 0 => any.
Optional green and blue images. They are used only if DOCOLOR
> 0 and the INNAME file does not have RGB as its third axis.
IN3NAME.....Image name for green. Standard defaults.
IN3CLASS....Image class for green. Standard defaults.
IN3SEQ......Image seq. # for green. 0 => highest.
IN3DISK.....Disk unit # for green. 0 => any.
IN4NAME.....Image name for blue. Standard defaults.
IN4CLASS....Image class for blue. Standard defaults.
IN4SEQ......Image seq. # for blue 0 => highest.
IN4DISK.....Disk unit # for blue. 0 => any.
BLC.........Bottom Left Corner of grey-scale image (0,0) means
(1,1). The contour image window is the same size as the
grey image window, but a smaller window will be selected
if needed to overlap the images. See DOALIGN.
TRC.........Top Right Corner of grey-scale image: (0,0) means top
right corner of map. NOTE: for the grey-scale image
TRC(3-7) is set to BLC(3-7) since only one plane is
shown. If the contour image is a cube, TRC(3) is taken
to select the plane of that cube to be used for
contouring. This allows a contour image of one plane to
overlay a grey image of anther plane of the same cube.
XYRATIO.....The ratio of the X-axis to Y-axis pixel separations.
0 => use ratio of axis increments or Y to X windows
PIXRANGE....Min,Max of Image intensity. 0 => entire range
FUNCTYPE....Image intensity transfer function
'LN' => linear = 1;
'LG' => log = 2;
'L2' => extreme log = 3;
'SQ' => square root = 4;
'NE' => negative linear = 5.
'NG' => negative log = 6;
'N2' => negative extra log = 7;
'NQ' => negative square root = 8;
others => linear.
APARM.......(1,2) PIXRANGE for green image 0 -> green image entire
range. Can also be used for green pixrange when
plotting an RGB image - default is PIXRANGE.
(3,4) PIXRANGE for blue image 0 -> blue image entire
range. Can also be used for blue pixrange when
plotting an RGB image - default is PIXRANGE.
(5) code number for FUNCTYPE of green image;
0 -> FUNCTYPE
(6) code number for FUNCTYPE of blue image;
0 -> FUNCTYPE
These are used when building an RGB truecolor image from
three independent images with DOCOLOR > 0.
LTYPE.......Labelling type, see HELP LTYPE for details:
1 = border, 2 = no ticks, 3 or 7 = standard, 4 or 8 =
relative to ref. pixel, 5 or 9 = relative to subimage
(BLC, TRC) center, 6 or 10 = pixels. 7-10 all labels
other than tick numbers and axis type are omitted.
Less than 0 is the same except that the plot file
version number and create time are omitted.
Add n * 100 to alter the metric scaling.
DOALIGN.....Controls how the grey and contour images are to be
aligned (see HELP DOALIGN). True (>.1) means that the
images must agree in their coordinates, though not
necessarily in the reference pixel position. Alignment
is by coordinate values (if DOALIGN > -0.1) or by
offsets from the reference pixel positions (if DOALIGN
<= -0.1). If DOALIGN < -1.5, alignement is at pixels
(1,1,...) ignoring the headers.
PLEV........Percent of peak for the contour increment. If PLEV and
CLEV are zero, 10 is used.
CLEV........Image intensity value for the contour increment.
Used only if PLEV = 0.
LEVS........Contour levels in units of the increment. The levels
must be in ascending order and a maximum of 30 levels
are permitted. 0 => -10,-9,-8,-7,-6,-5,-4,-3,-2,-1,
1,2,3,4,5,6,7,8,9,10,0
DOWEDGE.....If false (<= 0.0), do not plot a step wedge. If 1.5 >=
DOWEDGE > 0.0, then plot a wedge along the top of the
image using PIXRANGE range of values. If between 1.5 and
2.5, plot a wedge along the right-hand edge of the image
using PIXRANGE range of image values. If between 2.5 and
3.5, plot a wedge along the top with the full range of
image values. If between 3.5 and 4.5, plot a wedge along
the right hand edge with the full range of image values.
If LTYPE >= 3, ticks and tick labels are drawn for the
wedge. In true-color plots, the labeling is done for
the red image. DOWEDGE=3 or 4 is recommended in that
case.
DOCIRCLE....False (<= 0) means that tick marks are short lines
extending inward from the plot borders. True (>0)
requests that a full coordinate grid be drawn.
STVERS......Version number of ST (star position) file to be used to
plot star positions as plus signs.
0 => highest, < 0 => no star positions plotted
STFACTOR....Scale factor used to multiply star sizes in file
for plotting. = 0 => don't plot stars, < 0 also
plot any labels.
CBPLOT......Selects the corner in which the half-power beam plot is
placed
0: no beam plot
1: lower left
2: lower right
3: upper right
4: upper left
5: plots the beam in a separate pane
6 - 10: as 1-5 but slightly filled in
11 - 15: as 1-5 more filled in
16 - 20: as 1-5 scribbled over
CBPLOT = -n < 0 => use CBPLOT=n but do not plot any
contours, grey scale, or vectors in the Clean Beam area.
IN2VERS.....Start slice file version to overlay location
IN3VERS.....End slice file version to overlay location
NBOXES......Number of boxes to overlay
CLBOX.......Boxes to overlay
DOTV........> 0 => plot directly on the TV device, otherwise
make a plot file for later display on one or
more devices (including the TV if desired).
GRCHAN......Graphics channel (1 - 7) to use for line drawing.
0 => use multiple graphics planes for the various parts
of the graphical drawing.
TVCHAN......TV channel to display gray-scale portion of plot.
0 -> 1.
DODARK......When plotting on the TV (only), DODARK controls whether
contours, polarization lines, and stars are drawn as
black overlay lines when the grey-scale image is bright
(>0) or in the same color as used for the lines when the
image is not bright (<= 0).
DARKLINE....When the grey-scale image after FUNCTYPE and other
scaling (values 0 to 1) is > DARKLINE, dark lines are
used to draw polarization lines, stars, and contours.
<= 0, > 1 => 0.33.
TVCORN......TV pixel location (X,Y) where the bottom left corner of
the plot is to be placed. If either is zero, center the
plot. Pixel scaling is always used in GREYS.
OFMFILE.....' ' => plot in black and white
'TV' => read the TV OFM (before initializing it)
other => read a text file giving the OFM to use (as in
OFMDIR, OFMGET, OFMLIST, OFMSAVE).
OFMFILE may be of the form 'Logical:File' where Logical
is an logical (environment) name for a directory and
File is a file name. It may also be of the form
'Stdfile' which is either a file $OFMFIL/Stdfile.uuu
where uuu is the login user number or a file
$AIPSOFM/Stdfile.001 in the OFM area distributed with
AIPS. Use verb OFMDIR to show what is available in the
AIPSOFM and OFMFIL directories. There is a web site
http://www.nro.nao.ac.jp/~sawada/aipscb/
with color images of all standard AIPS OFMFILEs.
INFILE......If 'VLA' or 'VLBA' use layouts appropriate to those
arrays. Else if not blank, look for text files of name
INFILE.layout and INFILE.bolts to generate a line type 4
overplot showing the panel and bolt configuration. The
panel layout file has format
n ! card 1 gives number of circles
j Rin Rout ! n cards give number panels and their
inner and outer radii in units of
image
any number of cards may follow and are ignored. The
bolts file has format
n r ! card 1 gives number of bolt circles
and size of x mark
R j Theta0 ! n cards give bolt radius, number of
bolts and starting angle (CW, 0 up)
any number of cards may follow and are ignored. The
number of values shown above are read with free format
and anything following on the card is ignored. Values
must be separated by blanks not TAB characters.
